Frequently Asked Questions

The kernel build for my stock ROM isn't listed, which one do I use?

Use the build that is the closest match to your current build. If you look at the kernel version in Settings -> About Phone you will see a number after the letters 'CL' eg. CL123456. This is a change list version number.

Use this number to find the closest matching build using the lists below, without going outside your Android version. That means if your Android version is 2.3.3, ignore all the 2.3.4 and 2.3.5 kernels. If your Android version is 2.3.4, ignore all the 2.3.3 and 2.3.5 kernels. Lists for European and Australian builds can be found below to make it easier to determine which build you should use.

Example: Android version 2.3.3, change list number CL380123. The closest match would be the XWJVN kernel.

How do I enable or disable Voodoo Lagfix?

Method 1: To control the status of lagfix, download Voodoo Control Plus.

Method 2: Use Recovery mode to disable and enable Voodoo Lagfix.

Method 3: On your internal sdcard is a folder called "Voodoo". Inside this folder, create a blank file called "enable-lagfix" to enable lagfix. Create a blank file called "disable lagfix" to disable lagfix.

I want to stay on the RFS filesystem with the Voodoo kernel, how do I do this?

Create a folder on your internal sdcard called "Voodoo" then create a blank file called "disable lagfix" inside this folder BEFORE flashing the kernel.

How do I obtain root with this kernel?

The su binary is already included and Superuser.apk is pre-installed. You don't need to install anything extra.

Root is also available by default for adb and in recovery mode also.

Is there Voodoo Color in this kernel?

Voodoo Color is not available in this kernel as Voodoo Color requires the kernel to be built from sources.

Is there Voodoo Sound in this kernel?

Voodoo Sound is not directly included, however Voodoo Sound can be added by installing Voodoo Control Plus. If you wish to use PayPal you can grab it from YAAM.

By purchasing Voodoo Control Plus you are supporting supercurio's brilliant work.

How do I make use of the CIFS support?

To use CIFS, install CIFS Manager.

Open CIFS Manager and go to Settings.

Tick Load CIFS Module
Tick Load via insmod
Tap on Path to cifs.ko and enter exactly the following:

/lib/modules/slow-work.ko:/lib/modules/cifs.ko

Exit the app and re-open it. You can start adding your shares.

How do I make use of the app zip aligner?

You need to be running at least version 1.1 of the Voodoo kernel.

On your internal sdcard is a folder called "Voodoo". Inside this folder, create a blank files accordingly:

"enable-zipalign-system" to enable zipalign on next boot for /system/app
"enable-zipalign-data" to enable zipalign on next boot for /data/app

These files are automatically removed by the zipalign script once the script has finished running so that it does not run on every boot, which would result in a slow boot for users with a large number of apps.

What are the MD5 hashes for and how do I check my download against the provided hash?

Download and install HashTab which is a shell extension that will tell you the hash of a file. Simply right click the file, go to Properties and then the File Hashes tab.

I'm coming from another custom kernel. Are there any catches I need to be aware of?

The general rule is, if you have any other lagfixes enabled, you need to disable them first before flashing the Voodoo kernel.

What are the limitations of the nandroid backup/restore functionality in CWM?

- Do NOT restore nandroid backups created using CWM 2.x, 3.x or 4.x. The format is different.
- You MUST disable Voodoo Lagfix (convert back to rfs filesystem) before creating a nandroid backup or restoring a nandroid backup. Do NOT backup/restore with lagfix on.
- Nandroid backups of the /system partition where the backed up partition had less than 15MB of free space will not restore completely, due to the way the rfs filesystem works. This should only affect restoring a backup of a stock ROM.

This is great

Thanks!

Can u try implement JFS lagfix too ? Thanks

XXJVR odexed from semaphore kernel flashed this and it wont boot

I would suspect there is an incompatibility here - these kernels have been tested on stock ROMs coming from stock kernels.

Are you able to get into CWM? If you can, use adb to pull the /voodoo/logs folder, zip it up and attach it to your post so I can take a look into it.

Do you have anything in /system/etc/init.d ?

Edit: re-download the kernel, I fixed something very minor

JFS isn't all that popular- I may look at it later down the track but for the time being this is strictly a continuation of supercurio's work.

cantIntoCode · Aug 20, 2011

Awesome! I love voodoo kernels, seems you've taken the extra step to really show how to make things shine! Well done!

currydude · Aug 20, 2011

Nice work here Alan

I will be working your work closely! haha.

Revert back to RFS filesystem before flashing to this kernel. This is working on my personalised odexed and deodexed roms.

Yes I could go to CWM, and I dont have init.d folder at all

Now it's ok

Could you add voodoo color so that user can calibrate color, thanks.
It's buttery smooth, on pair with Semaphore kernel.

Did that before, but thanks anyway

Nice work. Added your thread to my subscription.

Did you try a different USB port? Different Odin?

Try the flashing through CWM? (Removed by O.P.'s request. Please refer to 1st post.)

Man, great thanks, latest version works, just hope that Voodoo color will be implemented in the next release

madrooster · Aug 20, 2011

Voodoo color needs to be patched into the source and would require I re-base the kernel and build from sources. I will eventually look at moving to sources but there is a lot of work involved in doing that. I'm tight on time at the moment also so it'll depend on what free time I can throw at it.

Other I9000 owners - I am happy to look at building Voodoo kernels based on other kernels (ie. non generic Europe), if there is enough demand for it. Same applies to I9000T and I9000M models. Please post if you are interested in one as well as what kernel.

What's the main diference/benefit to flash this vs for instance the CF-root kernel ?

Sorry for my ignorance

demon_da · Aug 21, 2011

Thanks For Ur Great Work Man
Keep'em Comin

Sorry for my ignorance

Both are essentially doing the same thing:
-CWM
-Root
-Busybox
-Lagfix (Ext4 conversion).

The mechanism however and the methodology for lagfix though is different and different CWM versions. This having a more recent version.

currydude · Aug 22, 2011

I'm getting excellent battery life with this kernel! Keep up the great work

And finally, no more RAM/memory leakage.

kunjar · Aug 22, 2011

Flashed JVR stock as posted by Ramad, then flashed JVR Voodoo kernel using odin. My phone is like a rocket. Works solid indeed. Definitely notice a huge improvement even though the newer firmware's released by Samsung are much quicker. Browsing through the market is no longer laggy, can browse flash-heavy websites, Asphalt 6 loads quicker, controls respond much better, .etc

Coupled with Voodoo control plus my dead SGS feels like a brand new piece of hardware.

Thanks bro.
